Acharya Prashant explains that the human mind naturally tends to wander toward the external world, but its true benefit lies in returning to its source, often referred to as going within or moving toward the heart. He clarifies that going within does not mean following an abstract command but is a practical matter of profit and loss. A restless mind only increases its suffering by running outward. Instead of focusing on what a desire demands, one should investigate where the desire originates. This process of tracing the senses back to their source is true introspection. He notes that while the mind often obtains what it desires, it never finds lasting satisfaction, leading to a cycle of slavery to worldly objects.
